Miradry Post-procedure Patient Instructions

You have just received your miraDry procedure. As you leave the physician’s office today, there are a few things that you should know.

First of all, you should notice a reduction in your underarm sweat almost immediately after the procedure. Most patients report a reduction of 60%, but not complete elimination, of their underarm sweat. In a recent clinical study, the average sweat reduction was 90% after their second treatment.

It is normal for the underarms and surrounding areas to feel numb for several hours after the procedure; sometimes this numbness can also be felt in the arms for a few hours.

Swelling in the treated area is normally seen for up to two weeks after the procedure, though this swelling can be reduced by regularly applying ice as directed by your physician’s office.

Your physician will also recommend a non-prescription anti-inflammatory medication such as ibuprofen to reduce the normal inflammation and discomfort that usually occurs for a few days after the procedure.

Although usually not needed, if you wish to apply antiperspirant/deodorant, you can typically resume doing so within a few days following the procedure. Your underarms could be tender for up to two weeks as they heal from the procedure. Shaving can also resume when the tenderness has subsided enough for your comfort level.

Other minor effects can last several weeks: swelling in the arm or torso; altered sensation (numbness or tingling) in the skin of the treated area or the arm; redness or bruising in the underarm or adjacent area. Other minor effects that may last longer are bumps you can feel under the skin, darkening of the skin, and altered sensation in the skin in and around the treated area. These should gradually disappear over time. Partial hair loss may be long-term.

Though less common, it is possible that some small blisters may develop in the treatment area. Keeping these areas clean and applying an over-the-counter antibiotic ointment can speed the healing process and prevent infection.

You should call your doctor if you:

develop signs of infection (pain, heat or surrounding redness) that lasts more than a week or appears to be getting worse

are experiencing significant pain that is not relieved by the recommended pain medication listed above

develop severe swelling, redness, or bruising that is not getting better after two weeks
